Error in Visual Studio when formatting with no newline at end of file

[AdamYoblick]

When trying to format a document in Visual Studio using the autopep8 formatter, an error is thrown when there is no newline at the end of the file. Please see microsoft/PTVS#6752 for details.

Python Code (remove the newline at the end!!!)

######this is a comment
import os,sys;
spam( ham [ 1 ], { eggs : 2 } )
def foo    ():pass
x=1;y     =2;
y = 2
#comment no newline

The error looks like this:

Command Line and Configuration

Looks like the command is run by the PTVS extension here: https://github.com/microsoft/PTVS/blob/main/Python/Product/PythonTools/PythonTools/Editor/Formatting/PythonFormatterAutopep8.cs#L27

Your Environment

• Python version: 3.9.7
• autopep8 version: 1.5.7
• Platform: windows
